Vicoustic Iso Blanket 隔音毯

I was skeptical about limp-mass blankets for soundproofing, but the Iso Blanket's STC rating actually works—my noisy neighbors are now a faint muffle. It's dense enough to feel substantial yet easy to hang with the included grommets.

Hanging this in front of my home office door cut the neighbor's TV noise way down, and the limp-mass weight feels solid without being a hassle to drape. The STC difference between this and the Pro version made me think about my ceiling, but for a bedroom wall this does the job.

The STC rating on this limp-mass sheet is the real deal—my neighbor's bass thump dropped noticeably the day I hung it. I was worried about installation, but it cut easily and stayed put without sagging.
